EYE AND FACE SHIELD FOR EMERY AND GRINDING WHEEL OPERATORS.

Application filed December 14, 1923. Serial No. 680,622.

1 '0 all rv/1.0122, it may concern:

lle it known that I, lliiorrixs J. Kininmnni, a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful In'iprovements in Eye andFace ,more emery or grinding wheels, and ad justable so that atrai'isparent member thereof will be interposed between an emery orgrinding wheel and the face of an operator using said wheel for grindingor polishing purposes.

Among the objects of my invention is to obtain a'device of the kind.recited which is easily mounted on the base of floor grinders ofdifferent sizes, and whether the journal bearing of the emery wheel orgrinder is secured to said baseby one or two bolts on each side thereof;and in case said two bolts are used to secure said journal bearing tosaid base, said device may be secured in place regardless, within aconsiderable limit, of the variation in distance between said bolts inthe different makes and sizes of floor grinders and emery wheels. Anadditional object is to obtain a device of the kind recited which iseasily mounted in place adjacent to an emery or other abrading wheel, orwheels, upon a wall or post, and which, when mounted, can be readilypositioned to suit the needs of the operator, so as to protect his eyesand face from sparks or other material thrown off by the contact of thearticle which is being ground or polished by its being forced intocontact with the revolving emery wheel or other abrading surface; saiddevice being provided with a transparent member which is positioned soas not to interfere with a view of the material being operated on. Anadditional object is to obtain a device which may be mounted at the rearof the emery or other abrading wheel, and the transparent member thereofmay be adjusted to'a desired position and angle in front of said emeryor other abrading wheel. An additional object is to obtain a device ofthe kind recited which can be adjusted in a desired positlon by theoperator without recourse to bolts or nuts to maintain the transparentmember thereof in said adjusted position. An additional object is toobtain a device of the kind recited whiehis econon'iically made,durable, and not liable to breaker to get out of order.

Floor emery wheels or grinders to which this apparatus is speciallydesigned to be attached are made by several manufacturers and in anumber of different sizes, in all, however, so far as I am advised,there is a standard having a table or base at the upper end thereof anda journal bearinghaving a base resting on and secured to said table bybolts. floor emery wheels or grinders there is a bolt in the rear of thebase of the journal hear ing, extending through said base and into saidtable, and an additional bolt extending through said base and into saidtable in front of said standard; while in the larger sizes of said flooremery wheelsor grinders, there are a plurality of bolts both in the rearand in front of the standard of the journalbearing extending through thebase thereof and into the table of the floor stand. Where a plurality ofbolts in front and rear of the standard thereof are used to attach thejournal bearing to a table the distance between said bolts varies withthe different makes, there being no standard with reference thereto. Ihave therefore designed a base forming an element of my invention whichcan be secured to the base of the journal bearing of all makes of flooremery wheels or grinders that I am at present advised of, by simplyremoving one or two of the bolts attaching the base of the journalbearing to the table of the floor stand, placing said base of my deviceon the base of the journal bearing and replacing the bolts or boltpreviously removed therefrom, or substituting a bolt ofthe same size butof slightly greater length, in place of said removed bolts; and at thesame time I obtain a base which is attachable to a vertical wall or postby one or two bolts, as preferred. I

In the drawing referred to Fig. 1 is a side elevation of the upper endof a floor stand, a journal bearing secured thereto, an emery orgrinding wheel the shaft whereof is rotatably mounted in said journalbearing, and an eye and face shield em- In the smaller sizes of some ofsaid bodying this invention mounted thereon by a single bolt extendingthrough the base of the device, the base of said journal bearing andinto the table of the floor stand.

Fig. 2 is a top plan view of the base of the device attached to the baseof the journal illustrated in Fig. 1, by a plurality of bolts,

showing a portion of one end of said journal base in top plan view and aportion of a vertical m'ember forming an element" o'fthe device inhorizontal section.

Fig. 3 is a side elevation of the base'of" the device, attached to thebase of a journal bearing, as in Fig. 2 and showing in vertical section,a portion of said-base of the journal bearing, and in .side elevation ashort section of a vertical member forming an element of the device.

Fig. at is a top plan view of the base of the device and ofa portionofthe base of a journal bearin anda horizontal sectionof a verticalmember of the device; said parts beingassenibled in the mannerillustrated in 1.

Fig. 5 is a side elevation ofthe several parts which are illustrated inFig. 1, with the base of the device turned 180 from the position thereofwhich is illustrated in Fig.1

Fig. 6 is aside elevation of a section ot-a wall, or post, and of thebase otthe device attached thereto by a plurality oiibolts, and

nate a given part indicates said upper part throughout the severalfigures of the drawing wherever'the same appears.

1, Fig. 1, represents the upper endofthe standard of a floor stand, 2represents a table at the upper end of. standard 1. 3

represents the base of a journal bearing, 4; the standard of saidjournal bearing and 5, 6,bo:lts extending through said base 3, with thescrew threadson said bolt fittingfinto corresponding screw threads in anaperture in-table 2, thereby attachingsaid journal bearing to saidtable. 7, 8, respectively represent the members of a two part base fornring an element ot'the invention. 9, 9, represent a reverse bend inmembers 7 and'S. Where the base members 7, 8, are attached to a table bya single bolt, as 6, Figs. 1, t

and 5, said members are arranged one over the other, as is wellillustrated in Figs. 1 and 5, and the bolt 6 is extended-throughapertures in both of said members, and into the table 3 and into a screwthreaded aperture in table 2. III-grouping the members 7 and 8 as abovedescribed it is immaterial whether said members are attached to table orbase 3 and table 2 in such manner that the unattached ends thereof arein planes lower than the planes of the attached ends,

as is illustrated in Fig. 1, or whether said unattached ends are inplanes which are above or higher than the planes of the attached ends,as is illustrated in Fig. WVhere the two part base formed by 1nembers 7and 8 are attached to base 3 by two bolts, 6, (3', as is illustrated inFigs, 2 and 3, one of the members 7 and 8 is turned, say from theposition in which it is illustrated in Fig. 5, so that the side thereofopposite to the side in contact with said table, 3, in said Fig. is incontact with said table, the other of said members (8), being in thesame relative position to table 3 as in said Fig. 5;b'u't in contacttherewith. 1O represents a vertical standard of the device, andpreferably consists ot'a pipe or tubescr'ew threaded at both endsthereof, as at 11, Fig.

1, the lower one of said ends fitting into coire'sp'on'c'ling screwthreads in an aperture in said members 7 and 8, thereby firmly securingsaid standard in said base. 12'represents a ti 'ible member well knownin the art of electric lighting, and comprising a coil of resilient wirewithin a coilof wire of tensile material, which is not resilient, saidouter coil being made of wire which is substantially triangular'in crosssection, and wound closely to the coil of resilient wire. Theconstruction of this flexible member forms no part of my invention, andso is not illustrated in detail. represents a head which is liri'nlysecured to one end of the flexible me'1'nber12, and is provided within"- ternal screw threads fitting tightly on to screw threads 11 on theupper end o'f sta'ndar'd 15 represents what is known in the artofpipin'g as a' drop elbow, which is provided with lugs or ears 16, 16;said lugs haji' in'g apertu s through which bolts, 17', 17, are extendedto securesai'd drop elbow to any desired base. 8, 18, rcspecti elyrepresent nuts on bolts 17, 1?. It will be 01 served on comparisonotFigs. 1 and 7, that the drop elbow 15 is turned in Fig. 7 from theposition in which it is illustrated in Fig.

1,-so'that'one ot said lugs 16, and bolts 17 are shown in F 1, theother'ones thereof are shown in F 1g. '7. One end of the flexible member12 15 secured. in one (19) end of drop elbow 15, in Fig. 1, and into theother (20) end thereof in F T. 21, Fig. 1, and 22', Fig. 7 represents aii'ame and a inodili cation of said frame. Frames 21, 22, enclose atransparent plate 23, the upper end of llt) lugs or ears 16, 16, areapplied to one side of the frame and secured thereto by bolts 17, 17 andnuts 18, 18, as hereinbefore recited; or by other suitable means, asrivets. Whichever form of frame is adopted, the plate 23, of transparentmaterial is not necessarily changed in size, or shape.

here it is desired. to attach the members 7, 8, of the two part base ofmy device to a vertical wall or post, said members may well be broughtinto the same relative position as is illustrated in Figs. 2 and 3, andattached to said wall or post by bolts (5, (3, as is illustrated in Fig..(5. The slight variation of said members from a vertical plane notaffecting the etlieiency of said members as a base. 24, Fig. (3,represents a street elbow, which is interposed between the lower end ofstandard 10, and said members 7 8, when said members are insubstantially vertical planes; one end of said street elbow being screwthreaded in the ordinary way, and lit- I ting into corresponding screwthreads pro- 'vided therefor in apertures in said members 7 and 8. Byinterposing the street elbow 24-, the standard is mounted and maintainedin a substantially vertical position, as in Figs. 1, 3 and 6. It isevident that where the members 7, 8, are attached to a vertical wall orpost by a single bolt, said members may be placed in the same relativeposition as they are illustrated in Fig. 5, and the bolt extendedthrough apertures in said members and into the vertical wall or post inthe same manner and direction as bolt 6' in said Fig. 5, extends throughapertures therein and into table 3. lVhen so secured to a vertical wallor post both ends of members 7, S, will be in planes parallel to theplane of the wall or post, and the street elbow 2% will be attached tosaid members 7, 8, in the same manner as is illustrated in Fig. 6. Itwill be noted that by my constructing a two part base of members 7, 8,in the manner hereinbefore described, said base is attachable either toa horizontal table or to a vertical wall or post by one or two bolts andthat when two bolts are used the distance from one thereof to the othermay vary by a considerable amount with a corresponding difference in theangular relation of said members 7, 8.

I find, in practice, that where one end of the flexible member 12 issecured to a vertical member, as standard 10, and said flexible memberis bowed or curved so that the other end thereof is in an inclinedplane, say substantially as illustrated in Fig. 1, said flexible memberwill retain said position, the weight of the several. parts on theinclined end thereof not being sutlicient to change the position of saidflexible member 12 throughout the body part thereof, or at said inclinedend; and that the frame 21, (or 22), will not be moved from an adjustedposi- ,members of the device being simple, and

having been. hereinbefore recited, no further explanation thereofappears desirable or necessary.
